Bi-level Optimization of Distribution Network Considering Demand Response and Soft Open Point Integration Under Carbon Trading Mechanism
摘要
Abstract
Aimed at the problems such as power fluctuations,voltage instability and high operating costs caused by the integration of distributed generation into distribution network,a bi-level optimization strategy integrating demand re-sponse and soft open point in distribution network is proposed.First,a stepped carbon trading mechanism is adopted,and a bi-level optimization model considering demand response and soft open point is constructed.The lower-level mod-el aims to minimize the voltage deviation,while the upper-level model aims to minimize the comprehensive operating cost of the system.Second,a hierarchical optimization method is applied,in which the optimal voltage deviation ob-tained from the lower-level model is added by a small value and used as a stability constraint for the upper-level model.Third,by introducing auxiliary variables and second-order cone relaxation technology,the non-convex distribution net-work optimization model is transformed into a mixed-integer second-order cone programming model and solved.Based on the aforementioned research,case studies are conducted on a IEEE 33-node distribution system.Results demon-strate that the proposed strategy not only ensures system voltage stability but also achieves low-carbon economic opera-tion.关键词
